The influence of the conservation status and changes in the rainfall regime on forest-savanna mosaic dynamics in Northern Brazilian Amazonia
Exposing the spin-glass ground state of the nonsuperconducting La<sub>2-x</sub>Sr<sub>x</sub>Cu<sub>1-y</sub>Zn<sub>y</sub>O<sub>4</sub> high-T<sub>c</sub> oxide
We have studied the spin glass behaviour of non-superconducting
LaSrCuZnO (). As in the
superconducting analogues of these samples the spin glass transition
temperature decreases with increasing , and vanishes at . A
local enhancement in at is also observed and attributed to
stripe ordering. The disappearance of for is discussed in
terms of a quantum phase transition.Comment: Text, 4 figure
QTL analysis of flag leaf in barley (Hordeum vulgare L.) for morphological traits and chlorophyll content*
To understand genetic patterns of the morphological and physiological traits in flag leaf of barley, a double haploid (DH) population derived from the parents Yerong and Franklin was used to determine quantitative trait loci (QTL) controlling length, width, length/width, and chlorophyll content of flag leaves. A total of 9 QTLs showing significantly additive effect were detected in 8 intervals on 5 chromosomes. The variation of individual QTL ranged from 1.9% to 20.2%. For chlorophyll content expressed as SPAD value, 4 QTLs were identified on chromosomes 2H, 3H and 6H; for leaf length and width, 2 QTLs located on chromosomes 5H and 7H, and 2 QTLs located on chromosome 5H were detected; and for length/width, 1 QTL was detected on chromosome 7H. The identification of these QTLs associated with the properties of flag leaf is useful for barley improvement in breeding programs
